One deterministic module has affine ranking function ((199 * x) + (-2 * y)) and consists of 4 locations. One deterministic module has affine ranking function (1073742019 + (2 * y)) and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.9s and 3 iterations.
